• 1 1/2 cups low-sodium chicken broth
• 3/4 cup whole milk
• 1/2 cup sour cream
• 1/2 cup shredded cheddar cheese

• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt, or to taste
• 1/4 teaspoon freshly ground black pepper
• 1 tablespoon chopped fresh parsley, optional

How to Make Creamy Chicken and Biscuit Casserole

Step 1: Preheat the Oven

Preheat the oven to 375°F (190°C). Lightly grease a 9-by-13-inch glass or ceramic baking dish with butter or nonstick cooking spray.

Step 2: Sauté the Onion and Garlic

Melt 3 tablespoons butter in a large skillet over medium heat. Add the diced onion and cook for approximately 3–4 minutes, until softened.

Stir in the minced garlic and cook for another 30 seconds, just until fragrant.

Step 3: Make the Cream Sauce

Sprinkle the flour over the onion mixture and stir continuously for about 1 minute.

Gradually pour in the chicken broth while whisking to prevent lumps. Add the milk and continue stirring until the sauce begins to thicken, approximately 3–5 minutes.

Step 4: Add the Creamy Ingredients

Reduce the heat to low. Stir in the sour cream, shredded cheddar cheese, Italian seasoning, garlic powder, salt, and black pepper.

Mix gently until the cheese melts and the sauce becomes smooth. Avoid boiling the sauce after adding the sour cream.

Step 5: Add the Chicken

Fold the cooked chicken pieces into the creamy sauce, making sure every piece is evenly coated.

Cook for another 1–2 minutes, stirring gently. Add fresh parsley if desired.

Step 6: Fill the Baking Dish

Transfer the creamy chicken mixture into the prepared baking dish and spread it into an even layer.

The filling should be thick and creamy but still easy to spoon.

Step 7: Prepare the Biscuits

Separate the refrigerated biscuits and cut each one in half horizontally to make thinner rounds.

Arrange approximately 10 biscuit halves evenly over the chicken filling, leaving a little space between them. Reserve the remaining halves for another use or bake them separately according to package directions.

Using thinner biscuit pieces helps the centers bake through while the tops become golden.

Step 8: Add the Butter Topping

In a small bowl, combine the melted butter and garlic powder. Brush the mixture over the biscuit tops.

Sprinkle with grated Parmesan cheese if desired.

Step 9: Bake Until Golden

Place the baking dish on the center oven rack and bake uncovered for approximately 30–35 minutes.

The casserole is ready when the filling is bubbling, the biscuit tops are golden brown, and the biscuit centers are fully baked with no raw dough remaining.

If the biscuits brown too quickly, loosely cover the dish with aluminum foil during the final minutes.

Step 10: Rest and Serve

Remove the casserole from the oven and allow it to rest for 5–10 minutes before serving.

Spoon the creamy chicken filling onto plates with a golden biscuit on top. Serve warm.

Tips for the Best Chicken Biscuit Casserole

• Use cooked chicken: Rotisserie chicken or leftover baked chicken saves preparation time.
• Keep the sauce thick: A thick filling prevents the biscuits from becoming soggy.
• Cut biscuits into thinner pieces: This helps them bake more evenly.
• Leave space between biscuits: The dough needs room to expand.
• Check the biscuit centers: Golden tops alone don't guarantee the dough is cooked through.
• Let the casserole rest: Resting allows the sauce to thicken slightly before serving.

Delicious Recipe Variations

Add 1 1/2 cups thawed frozen mixed vegetables, such as peas, carrots, and corn, to the chicken filling.

Cheesy Chicken Biscuit Bake

Increase the cheddar cheese to 1 cup for a richer, cheesier sauce.

Creamy Garlic Chicken Casserole

Add two additional minced garlic cloves for a more pronounced garlic flavor.

Sauté 8 ounces sliced mushrooms with the onion before preparing the cream sauce.

What to Serve with Chicken and Biscuit Casserole

Because this casserole is rich and filling, it pairs beautifully with simple vegetable sides.

• Steamed green beans
• Roasted broccoli
• Fresh garden salad
• Honey-glazed carrots
• Roasted asparagus
• Simple cucumber salad

Storage and Reheating

Refrigerator

Allow leftovers to cool briefly, then refrigerate in airtight containers within 2 hours. Store for up to 3–4 days.

Freezer

The creamy chicken filling can be frozen separately for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating and adding fresh biscuit dough.

Freezing the fully assembled casserole may soften the biscuit topping.

Reheating

Reheat leftovers in a covered baking dish at 325°F (165°C) until the center reaches 165°F (74°C). Remove the foil briefly near the end to help the biscuit topping regain some texture.

Frequently Asked Questions

Can I use rotisserie chicken?

Yes. Shredded or chopped rotisserie chicken works beautifully and makes the recipe even easier.

Can I use homemade biscuits?

Absolutely. Homemade biscuit dough can be used instead of refrigerated biscuits. Adjust the baking time according to the dough's thickness.

Why are my biscuits doughy underneath?

Thick biscuit dough placed directly on a moist filling can take longer to cook. Use thinner pieces, leave space between them, and bake until the centers are fully cooked.

Can I make this casserole ahead of time?

Yes. Prepare the chicken filling in advance and refrigerate it. Reheat the filling until hot, transfer it to the baking dish, add fresh biscuit dough, and bake as directed.

Can I use cream of chicken soup?

Yes. For a shortcut version, replace the homemade cream sauce with condensed cream of chicken soup thinned with a little milk or broth. Adjust the seasonings because canned soup often contains added salt.

Final Thoughts

This easy creamy chicken and biscuit casserole combines tender chicken, a rich savory sauce, and fluffy golden biscuits in one comforting baked dinner.

With simple ingredients and family-friendly flavors, it's a delicious choice for weeknight meals, cozy weekends, and gatherings around the dinner table.
